BEC superpositions in twin wells

چکیده
The idea of a macroscopic entity simultaneously existing in two distinct possible states was introduced by Erwin Schrödinger in 1935, as a Gedanken experimental demonstration of the absurdity of quantum mechanics [1]. Since then, evidence has mounted that reality is as absurd as quantum mechanics suggests, with persistent currents (of a few μA) of opposite circulation having been detected in SQUIDS [2]. The fact that Bose-Einstein condensates are mesoscopic quantum entities which can be trapped in tunnel-coupled double wells seems to make them an attractive candidate for the demonstration of mesoscopic superpositions.

Vortex phase qubit: generating arbitrary, counterrotating, coherent superpositions in Bose-Einstein condensates via optical angular momentum beams.
We propose a scheme for the generation of arbitrary coherent superpositions of vortex states in Bose-Einstein condensates (BEC) using the orbital-angular-momentum states of light. We devise a scheme to generate coherent superpositions of two such counterrotating states of light using well-known experimental techniques. We show that a specially designed Raman scheme allows for transfer of the op...
متن کاملTesting quantum superpositions of the gravitational field with Bose-Einstein condensates
We consider the gravity field of a Bose-Einstein condensate in a quantum superposition. The gravity field then is also in a quantum superposition which is in principle observable. Hence we have “quantum gravity” far away from the so-called Planck scale. Typeset using REVTEX 1 The existence of macroscopically distinguishable superpositions in Bose-Einstein condensates (BEC) have been discussed b...

We recently proposed a scheme for the creation of coherent superpositions of vortex states in Bose-Einstein condensates BECs using orbital angular momentum OAM states of light Phys. Rev.

Here we discuss further technical details of the proposal, provide an alternative, time-reversalsymmetric scheme for transfer of a superposition of OAM states of light to the BEC via a p...
متن کاملExperimental study of the role of atomic interactions on quantum transport.
We report an experimental study of quantum transport for atoms confined in a periodic potential and compare between thermal and Bose-Einstein condensation (BEC) initial conditions. We observe ballistic transport for all values of well depth and initial conditions, and the measured expansion velocity for thermal atoms is in excellent agreement with a single-particle model. For weak wells, the ex...
متن کاملBose-Einstein condensation and superfluidity of trapped polaritons in graphene and quantum wells embedded in a microcavity.
The theory for spontaneous coherence of short-lived quasiparticles in two-dimensional excitonic systems is reviewed, in particular, quantum wells (QWs) and graphene layers (GLs) embedded in microcavities. Experiments with polaritons in an optical microcavity have already shown evidence of Bose-Einstein condensation (BEC) in the lowest quantum state in a harmonic trap. The theory of BEC and supe...
